2008-08-22Parallel Port Direction Fixaurel32
The direction bit in the control register should not be directly set using PPWCONTROL. The kernel gives the following debug message. parport0 (ppdev0): use data_reverse for this! More over setting the data pins to forward mode does not work, perhaps a bug in the Linux PP driver. The right way to do this is to use PPDATADIR to set the direction. The patch checks if the user is toggling the direction bit, and invokes PPDATADIR to do the job.

2008-08-21Handle terminating signals (Gerd Hoffmann)aliguori
This patch makes qemu handle signals better. It sets the request_shutdown flag, making the main_loop exit and qemu taking the usual exit route, with atexit handlers being called and so on, instead of qemu just being killed by the signal. To avoid calling vm_start() from the signal handler main_loop() got an additional check so qemu_system_shutdown_request() works even when the vm is in stopped state.

2008-08-21uhci: fixes for save/load-vm (Max Krasnyansky)aliguori
For some reason we were not registering save/load-vm handler for piix3 flavor of UHCI and hence save/load was broken. Async transactions need to be canceled when we save the VM because there is no way we can save/restore all that state. Since we do not mess the original TD/QH the driver will simply resubmit the transfers. Tested with Windows XP-SP2 running under QEMU/KQEMU.

2008-08-21husb: rewrite Linux host USB layer, fully async operation (Max Krasnyansky)aliguori
This is a follow up to the async UHCI patch. Both BULK and ISOC transactions are now fully asynchrounous. I left CONTROL synchronous for now, ideally we want it to be async too and it should not be that hard to do now. This patch obviously requires UHCI patch. The combo has been tested with various devices. See the UHCI patch description for list of the devices. Most of the testing was done with the KVM flavor of QEMU.

2008-08-21uhci: rewrite UHCI emulator, fully async operation with multiple outstanding ↵aliguori
transactions (Max Krasnyansky) This is esentially a re-write of the QEMU UHCI layer. My initial goal was to support fully async operation with multiple outstanding async transactions. Along the way I realized that I can greatly simplify and cleanup the overall logic. There was a lot of duplicate and confusing code in the UHCI data structure parsing and other places. We were actually violating UHCI spec in handling async ISOC transaction (host controller is not supposed to write into the frame pointer). The reason I wanted to support fully async operation is because current synchronous version is unusable with most devices exported from host (via usb-linux.c). Transactions take a long time and the whole VM becomes slow as hell. Current async support is very rudimentory and for the most part non-functional. Single transaction at a time is simply not enough. I have a device for which XP driver submits both IN and OUT packets at the same time. IN packet always times out unless OUT packet makes it to the device. Hence we must be able to process both in order for that device to work. The new code is backwards compatible and was first tested agains original synchronous usb-linux.c and builtin usb devices like tablet which is also synchronous. Rewrite of the usb-linux.c is coming up next. Async support was tested against various XP versions (ie XP, SP2, SP3) and a bunch of different USB devices: serial port controllers, mice, keyboard, JTAG dongles (from Xilinx and Altera). ISOC support was only lighly tested and needs more work. It's not any worse than current code though. UHCI parser changes are probably somewhat hard to review without the understanding of the UHCI spec. The async design should be fairly easy to follow. Basically we have a list of async objects for each pending transfer. Async objects are tagged with the original TD (transfer descriptor) address and token. We now support unlimited number of outstanding isoc and one outstanding bulk/intr/ctrl transfer per QH (queue head). UHCI spec does not have a clear protocol for the cancelation of the trasfer requests. Driver can yank out TDs on any frame boundary. In oder to handle that I added somewhat fancy TD validation logic logic to avoid unnecessary cancelations.

2008-08-21husb: support for USB host device auto connect (Max Krasnyansky)aliguori
QEMU can now automatically grab host USB devices that match the filter. For now I just extended 'host:X.Y' and 'host:VID:PID' syntax to handle wildcards. So for example if you do something like usb_add host:5.* QEMU will automatically grab any non-hub device with host address 5.*. Same with the 'host:PID:*', we grab any device that matches PID. Filtering itself is very generic so we can probably add more elaborate syntax like 'host:BUS.ADDR:VID:PID'. So that we can do 'host:5.*:6000:*'. Anyway, it's implemented using a periodic timer that scans host devices and grabs those that match the filter. Timer is started when the first filter is added. We now keep the list of all host devices that we grabbed to make sure that we do not grab the same device twice. btw It's currently possible to grab the same host device more than once. ie You can just do "usb_add host:1.1" more than once, which of course does not work. So this patch fixes that issue too. Along with auto disconnect patch that I send a minute ago the setup is very seamless now. You can just allocate some usb ports to the VMs and plug/unplug devices at any time.

2008-08-21husb: support for USB host device auto disconnect (Max Krasnyansky)aliguori
I got really annoyed by the fact that you have to manually do usb_del in the monitor when host device is unplugged and decided to fix it :) Basically we now automatically remove guest USB device when the actual host device is disconnected. At first I've extended set_fd_handlerX() stuff to support checking for exceptions on fds. But unfortunately usbfs code does not wake up user-space process when device is removed, which means we need a timer to periodically check if device is still there. So I removed fd exception stuff and implemented it with the timer.

2008-08-21Fix windows buildaliguori
Right now, the Windows build is broken because of NBD. Using a mingw32 cross compiler is also badly broken. This patch fixes the Windows build by stubbing out NBD support until someone fixes it for Windows. It also santizing the mingw32 cross compiler support by replacing the --enable-mingw32 option with a compiler check to determine if we're on windows or not. Also remove the weird SDL pseudo-detection for mingw32 using a cross compiler. The hardcoded sdl-config name is seemly arbitrary. If you cross compiler SDL correctly and modify your PATH variable appropriately, it will Just Work when cross compiling. The audio driver detection is also broken for cross compiling so you have to specify the audio drivers explicitly for now.

2008-08-20Kludge to support linux-user on a PPC64malc
Some headers (e.g. signal.h) include asm/elf.h and the chaos of macro redefinitions ensues, this kludge avoids it. Alternative way to fight that would be to change all ELF_XXX and some other definitions to QEMU_ELF_XXX or something to that effect. This patch concludes the quest for enabling linux-user on PPC64, however, since qemu_mallocz uses mmap and, at least on this system, mmap tends to return values that do not fit into 32bit, emulation for 32bit targets does not work without some hacks wich are to disgusting to commit (and as `man mmap' tells us MAP_32BIT is only implemented on X86_64) git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5037 c046a42c-6fe2-441c-8c8c-71466251a162
